Below is a manure value spreadsheet that will allow you to play with rates/acre, price of fertilizer, and manure analysis to help you determine the value of the manure you are applying or what is leaving the farm. Highlighted cells are where you can change inputs. There is a sulfur value in this as well. In figuring the nitrogen take credits from the nitrogen in the 18-46-0 and the nitrogen in the ammonium sulfate. The top big box has figures for applications needing phosphorus. The bottom box is if phosphorus if not needed.
Look it over if interested and contact David Tollberg at (615) 587-3860 with any questions. Prices used for fertilizer are examples.
